Pull networking fixes from Jakub Kicinski:
"Including fixes from bluetooth, bpf, can and netfilter.
A little larger than usual but it's all fixes, no late features. It's
large partially because of timing, and partially because of follow ups
to stuff that got merged a week or so before the merge window and
wasn't as widely tested. Maybe the Bluetooth fixes are a little
alarming so we'll address that, but the rest seems okay and not scary.
Notably we're including a fix for the netfilter Kconfig [1], your WiFi
warning [2] and a bluetooth fix which should unblock syzbot [3].
Current release - regressions:
- Bluetooth:
- don't try to cancel uninitialized works [3]
- L2CAP: fix use-after-free caused by l2cap_chan_put
- tls: rx: fix device offload after recent rework
- devlink: fix UAF on failed reload and leftover locks in mlxsw
Current release - new code bugs:
- netfilter:
- flowtable: fix incorrect Kconfig dependencies [1]
- nf_tables: fix crash when nf_trace is enabled
- bpf:
- use proper target btf when exporting attach_btf_obj_id
- arm64: fixes for bpf trampoline support
- Bluetooth:
- ISO: unlock on error path in iso_sock_setsockopt()

to work with software devices with lockless Tx
- tap: fix null-deref on skb->dev in dev_parse_header_protocol
- revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some
devices and breaks others
- netfilter:
- nf_tables: many fixes rejecting cross-object linking which may
lead to UAFs
- nf_tables: fix null deref due to zeroed list head
- nf_tables: validate variable length element extension
- bgmac: fix a BUG triggered by wrong bytes_compl
- bcmgenet: indicate MAC is in charge of PHY PM

Users of GNU ld (BFD) from binutils 2.39+ will observe multiple
instances of a new warning when linking kernels in the form:
ld: warning: arch/x86/boot/pmjump.o: missing .note.GNU-stack section implies executable stack
ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
ld: warning: arch/x86/boot/compressed/vmlinux has a LOAD segment with RWX permissions
Generally, we would like to avoid the stack being executable. Because
there could be a need for the stack to be executable, assembler sources
have to opt-in to this security feature via explicit creation of the
.note.GNU-stack feature (which compilers create by default) or command
line flag --noexecstack. Or we can simply tell the linker the
production of such sections is irrelevant and to link the stack as
--noexecstack.
LLVM's LLD linker defaults to -z noexecstack, so this flag isn't
strictly necessary when linking with LLD, only BFD, but it doesn't hurt
to be explicit here for all linkers IMO. --no-warn-rwx-segments is
currently BFD specific and only available in the current latest release,
so it's wrapped in an ld-option check.
While the kernel makes extensive usage of ELF sections, it doesn't use
permissions from ELF segments.

Now that the PMU is refreshed when MSR_IA32_PERF_CAPABILITIES is written
by host userspace, zero out the number of LBR records for a vCPU during
PMU refresh if PMU_CAP_LBR_FMT is not set in PERF_CAPABILITIES instead of
handling the check at run-time.
guest_cpuid_has() is expensive due to the linear search of guest CPUID
entries, intel_pmu_lbr_is_enabled() is checked on every VM-Enter, _and_
simply enumerating the same "Model" as the host causes KVM to set the
number of LBR records to a non-zero value.

Refresh the PMU if userspace modifies MSR_IA32_PERF_CAPABILITIES. KVM
consumes the vCPU's PERF_CAPABILITIES when enumerating PEBS support, but
relies on CPUID updates to refresh the PMU. I.e. KVM will do the wrong
thing if userspace stuffs PERF_CAPABILITIES _after_ setting guest CPUID.
Opportunistically fix a curly-brace indentation.

Add compile-time and init-time sanity checks to ensure that the MMIO SPTE
mask doesn't overlap the MMIO SPTE generation or the MMU-present bit.
The generation currently avoids using bit 63, but that's as much
coincidence as it is strictly necessarly. That will change in the future,
as TDX support will require setting bit 63 (SUPPRESS_VE) in the mask.
Explicitly carve out the bits that are allowed in the mask so that any
future shuffling of SPTE bits doesn't silently break MMIO caching (KVM
has broken MMIO caching more than once due to overlapping the generation
with other things).

Rename the tracepoint function from trace_kvm_async_pf_doublefault() to
trace_kvm_async_pf_repeated_fault() to make it clear, since double fault
has nothing to do with this trace function.
Asynchronous Page Fault (APF) is an artifact generated by KVM when it
cannot find a physical page to satisfy an EPT violation. KVM uses APF to
tell the guest OS to do something else such as scheduling other guest
processes to make forward progress. However, when another guest process
also touches a previously APFed page, KVM halts the vCPU instead of
generating a repeated APF to avoid wasting cycles.
Double fault (#DF) clearly has a different meaning and a different
consequence when triggered. #DF requires two nested contributory exceptions
instead of two page faults faulting at the same address. A prevous bug on
APF indicates that it may trigger a double fault in the guest [1] and
clearly this trace function has nothing to do with it. So rename this
function should be a valid choice.
No functional change intended.

Stop Xen timer (if it's running) prior to changing the IRQ vector and
potentially (re)starting the timer. Changing the IRQ vector while the
timer is still running can result in KVM injecting a garbage event, e.g.
vm_xen_inject_timer_irqs() could see a non-zero xen.timer_pending from
a previous timer but inject the new xen.timer_virq.

Disable SEV-ES if MMIO caching is disabled as SEV-ES relies on MMIO SPTEs
generating #NPF(RSVD), which are reflected by the CPU into the guest as
a #VC. With SEV-ES, the untrusted host, a.k.a. KVM, doesn't have access
to the guest instruction stream or register state and so can't directly
emulate in response to a #NPF on an emulated MMIO GPA. Disabling MMIO
caching means guest accesses to emulated MMIO ranges cause #NPF(!PRESENT),
and those flavors of #NPF cause automatic VM-Exits, not #VC.
Adjust KVM's MMIO masks to account for the C-bit location prior to doing
SEV(-ES) setup, and document that dependency between adjusting the MMIO
SPTE mask and SEV(-ES) setup.

Fully re-evaluate whether or not MMIO caching can be enabled when SPTE
masks change; simply clearing enable_mmio_caching when a configuration
isn't compatible with caching fails to handle the scenario where the
masks are updated, e.g. by VMX for EPT or by SVM to account for the C-bit
location, and toggle compatibility from false=>true.
Snapshot the original module param so that re-evaluating MMIO caching
preserves userspace's desire to allow caching. Use a snapshot approach
so that enable_mmio_caching still reflects KVM's actual behavior.

LEA is illegal, it can be encoded and fed to CPU. In which case real

kvm_fixup_and_inject_pf_error() was introduced to fixup the error code(
e.g., to add RSVD flag) and inject the #PF to the guest, when guest
MAXPHYADDR is smaller than the host one.
When it comes to nested, L0 is expected to intercept and fix up the #PF
and then inject to L2 directly if
- L2.MAXPHYADDR < L0.MAXPHYADDR and
- L1 has no intention to intercept L2's #PF (e.g., L2 and L1 have the
same MAXPHYADDR value && L1 is using EPT for L2),
instead of constructing a #PF VM Exit to L1. Currently, with PFEC_MASK
and PFEC_MATCH both set to 0 in vmcs02, the interception and injection
may happen on all L2 #PFs.
However, failing to initialize 'fault' in kvm_fixup_and_inject_pf_error()
may cause the fault.async_page_fault being NOT zeroed, and later the #PF
being treated as a nested async page fault, and then being injected to L1.
Instead of zeroing 'fault' at the beginning of this function, we mannually
set the value of 'fault.async_page_fault', because false is the value we
really expect.

Bug the VM if retrieving the x2APIC MSR/register while processing an
accelerated vAPIC trap VM-Exit fails. In theory it's impossible for the
lookup to fail as hardware has already validated the register, but bugs
happen, and not checking the result of kvm_lapic_msr_read() would result
in consuming the uninitialized "val" if a KVM or hardware bug occurs.

arch/arm64/net/bpf_jit_comp.c:1918:52:
error: subtraction of different types can't work (different base

This is because the variable branch in function invoke_bpf_prog and the
variable branches in function prepare_trampoline are defined as type
u32 *, which conflicts with ctx->image's type __le32 *, so sparse complains
when assignment or arithmetic operation are performed on these two
variables and ctx->image.
Since arm64 instructions are always little-endian, change the type of
these two variables to __le32 * and call cpu_to_le32() to convert
instruction to little-endian before writing it to memory. This is also
in line with emit() which internally does cpu_to_le32(), too.

follow_pud_mask() does not support non-present pud entry now. As long as
I tested on x86_64 server, follow_pud_mask() still simply returns
no_page_table() for non-present_pud_entry() due to pud_bad(), so no severe
user-visible effect should happen. But generally we should call
follow_huge_pud() for non-present pud entry for 1GB hugetlb page.
Update pud_huge() and follow_huge_pud() to handle non-present pud entries.
The changes are similar to previous works for pud entries commit
e66f17ff7177 ("mm/hugetlb: take page table lock in follow_huge_pmd()") and
commit cbef8478bee5 ("mm/hugetlb: pmd_huge() returns true for non-present
hugepage").

Patch series "Simplify hugetlb vmemmap and improve its readability", v2.
This series aims to simplify hugetlb vmemmap and improve its readability.
This patch (of 8):
The name hugetlb_optimize_vmemmap_enabled() a bit confusing as it tests
two conditions (enabled and pages in use). Instead of coming up to an
appropriate name, we could just delete it. There is already a discussion
about deleting it in thread [1].
There is only one user of hugetlb_optimize_vmemmap_enabled() outside of
hugetlb_vmemmap, that is flush_dcache_page() in arch/arm64/mm/flush.c.
However, it does not need to call hugetlb_optimize_vmemmap_enabled() in
flush_dcache_page() since HugeTLB pages are always fully mapped and only
head page will be set PG_dcache_clean meaning only head page's flag may
need to be cleared (see commit cf5a501d985b). So it is easy to remove
hugetlb_optimize_vmemmap_enabled().

It is not necessary to allocate contiguous physical memory for BPF
program buffer using kcalloc. When the BPF program is large more than
memory page size, kcalloc allocates multiple memory pages from buddy
system. If the device can not provide sufficient memory, for example
in low-end android devices [0], memory allocation for BPF program is
likely to fail.
Test cases in lib/test_bpf.c all pass on ARM64 QEMU.

git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- The most intrusive patch is small and changes the default allocation
policy for DMA addresses.
Before the change the allocator tried its best to find an address in
the first 4GB. But that lead to performance problems when that space
gets exhaused, and since most devices are capable of 64-bit DMA these
days, we changed it to search in the full DMA-mask range from the
beginning.
This change has the potential to uncover bugs elsewhere, in the
kernel or the hardware. There is a Kconfig option and a command line
option to restore the old behavior, but none of them is enabled by
default.

dma-iommu and iova code

This reverts commit 7d06fed77b7d8fc9f6cc41b4e3f2823d32532ad8.
This introduced vmem_mutex locking from vmem_map_4k_page()
function called from smp_reinit_ipl_cpu() with interrupts
disabled. While it is a pre-SMP early initcall no other CPUs
running in parallel nor other code taking vmem_mutex on this
boot stage - it still needs to be fixed.

Multi-gen LRU still isn't merged as we were waiting for mapletree to
stabilize. The current plan is to merge MGLRU into -mm soon and to
later reintroduce mapletree, with a view to hopefully getting both
into 6.1-rc1.
